- the PIV toolbox for MATLAB(tm):

MatPIV is a toolbox for Particle Image Velocimetry, made to run with MATLAB (by the Mathworks Inc). By using MATLAB as a foundation, MatPIV is practically platform independent, meaning that the code will run on any platform where MATLAB will run. MatPIV is supplied with source code under the terms of the GNU general public license manager (see below) which means that it is straightforward to write additions or to do personal modifications to the code.

Potential users should notice that while not strictly required, the Image Processing Toolbox is highly recommended.

Current version is MatPIV 1.6.1, which can be downloaded from the download-page.

MatPIV 1.6.1 is freeware distributed under the terms of the GNU general public license, and it comes with absolutely no warranty! People who would like a free copy should drop the author an email at matpiv At gmail D0t c0m.

Mar 17, 2006 - Long time no update. I have today opened the download section for free download (users no longer need to register). I am also working on the long avaited Version 1.7. Finally I've created a new gmail account to deal with all matpat related issues.

Mar 17, 2005 - There is a bug in Matlab 7 which causes the MatPIV function definewoco to crash. The bug and its fix is described here. Registered users can download a fixed version of definewoco in the download section.
Sep 27, 2004 - I have co-authored a paper with Todd Cowen of Cornell, USA, which will appear in an upcoming book called "PIV and Water Waves". The paper deals with the fundamental basics of PIV. Download here.
Aug 6, 2004 - The tutorial has again undergone minor changes. The big news today is that I've now published it in the Applied Mathematics eprint series at University of Oslo. The correct and official reference for the tutorial is now: J. Kristian Sveen: "An introduction to MatPIV v. 1.6.1", eprint series, Dept. of Math. University of Oslo, "Mechanics and Applied Mathematics", NO. 2 ISSN 0809-4403, August 2004. Here's a suggestion for BibTex-entry.
Aug 5, 2004 - A small error has been corrected in the tutorial.
Jul 17, 2004 - Version 1.6.1 has been released. Registered users may pick it up from the regular Download page.
Apr 16, 2004 - Version 1.6.1 will be ready for release in a few weeks. The major improvement will be a user-manual and a few updates to the code
Apr 16, 2004 - Added updated definewoco.m with several improvements. Registered users may pick up the file from the download-section
Feb 6, 2004 - More links added
Feb 5, 2004 - Updated the links and milestones pages. PTV is currently being tested and will be included in a forthcoming release (1.7).
